ABSTRACT

Methods, apparatus, and software are described for using an optically-readable code. The optically-readable code may be caused to be displayed. Data may be received based on the optically-readable code. Content or other items may be determined based on the optically-readable code.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation application of co-pending U.S.patent application Ser. No. 13/616,828 filed Sep. 14, 2012, and entitled“OPTICALLY READABLE CODES IN CONTENT DELIVERY SYSTEM,” the content ofwhich is hereby incorporated by reference.

BACKGROUND

Quick-response (QR) codes are commonly used to supplement advertisingand other informational content. QR codes represent website addresses,and so when a user of a device having a camera obtains an image of a QRcode, the device may determine the encoded website address and direct aweb browser to that address. While QR codes are useful for providingsupplemental information in this way, their full potential has yet to berealized.

SUMMARY

According to some aspects as described herein, a user of a contentconsumption device, such as a smart phone, display device, audio system,gaming console, computer, set top box, or digital video recorder, may beable to remotely program the content consumption device to record and/orotherwise obtain content by capturing an optically-readable code such asa quick response (QR) code using a different device such as a cellularphone having a camera. The optically-readable code may representparameters that could be used in a query of a database sufficient toreturn one or more items of content as a result of the query. Thedatabase may associate a plurality of items of content with a pluralityof characteristics, and the query may represent a uniform resourceidentifier (URI) including one or more parameters identifying one ormore values of at least some of the characteristics. The query resultsmay be returned via a website interface generated by a web server, andmay, for instance, return one or more items of content. The user maythen utilize the website to control the content consumption device torecord or otherwise obtain the one or more items of content.

According to further aspects as described herein, the web server oranother computer may receive the URI from the user device and perform aquery of the database based on the parameters (e.g., passed parameters)included in or with the URI. As stated above, the query results mayreturn one or more items of content. The web server may then indicatethe one or more items of content on the website user interface forselection by the user device.

According to still further aspects as described herein, an advertisermay create the optically-readable code by determining theabove-mentioned query sufficient to return the desired one or more itemsof content. The advertiser may, for instance, use a trial-and-errortechnique to determine the appropriate query, and may use as a startingpoint one or more known characteristics about the desired one or moreitems of content. Once the appropriate query is determined, anoptically-readable code may be generated containing the query asparameters in a URI.

According to yet further aspects as described herein, an on-demandand/or context-sensitive optically-readable code may be displayed to theuser of the content consumption device. The optically-readable code maydepend upon a status of the content consumption device, such as whichitem of content (and/or which portion of the item of content) iscurrently being displayed or otherwise presented by the contentconsumption device, and/or an error condition being experienced by thecontent consumption device. Thus, for example, the content consumptiondevice may determine a particular one or more optically-readable codesto be displayed that may be dependent upon the context of the item ofcontent currently being presented to the user, or an error condition.Moreover, the optically-readable code may be displayed on-demand, e.g.,in response to a user input indicating a desire to view informationrelated to the optically-readable code, or in response to detecting theerror condition. Thus, where the optically-readable code is presented ondemand to the user, the user may not need to see the optically-readablecode unless it is desired, which may in some cases help avoid confusionto some users and prevent blocking or reduction in size of video contentin order to otherwise display the optically-readable code. In addition,the on-demand and/or contextual optically-readable code may be formattedin a manner as described above by representing a URI includingparameters representing parameters in a database query.

According to still further aspects as described herein, a user device,such as a cellular phone, may be paired with a content consumptiondevice using an optically-readable code. For instance, the contentconsumption device may display an optically-readable code containingstatus information such as an identity of the content consumptiondevice, and the user device may read the optically-readable code and usethe identity (and/or other information represented by theoptically-readable code) in order to become authorized to control thecontent consumption device.

These and other aspects of the disclosure will be apparent uponconsideration of the following detailed description.

DETAILED DESCRIPTION

FIG. 1 illustrates an example network 100 on which many of the variousfeatures described herein may be implemented. Network 100 may be, orotherwise include, for example, any type of information access and/ordistribution network, such as a satellite network, a landline network, acellular telephone/data network or other wireless network, the Internet,a wide-area network, a local-area network, etc., or a combination orsubcombination thereof. Some examples include an optical fiber network,a coaxial cable network, or a hybrid fiber/coax (HFC) distributionnetwork. Such networks may use a series of interconnected communicationlinks 101 (e.g., coaxial cables, optical fibers, hybrid fiber/coax,wireless links, etc.) to connect multiple homes 102 to a networkequipment site 103 (which may be, e.g., a central office or headend, orother central location). The network equipment site 103 may transmitdownstream information signals onto the links 101, and each home 102 mayhave a receiver used to receive and process those signals.

There may be one or more physical links 101, such as an electricallyconductive line, originating from the network equipment site 103, whichmay be split a number of times to distribute the signal to various userlocations 102 (e.g., homes, businesses, schools, institutions etc.) inthe vicinity (which may be many miles) of the network equipment site103. The links 101 may include components not illustrated, such assplitters, filters, amplifiers, etc. to help convey the signal clearly,but in general each split introduces a bit of signal degradation.Portions of the links 101 may also be implemented with fiber-opticcable, while other portions may be implemented with coaxial cable, otherlines, or wireless communication paths.

The network equipment site 103 may include a termination system (TS)104, such as a cable modem termination system (CMTS), which may be acomputing device configured to manage communications between devices onthe network of links 101 and backend devices such as servers 106-107 (tobe discussed further below). The TS may be as specified in a standard,such as, in an example of an HFC-type network, the Data Over CableService Interface Specification (DOCSIS) standard, published by CableTelevision Laboratories, Inc. (a.k.a. CableLabs), or standards relatingto various optical networks such as passive optical network (PON)networks, or it may be a similar or modified device instead. The TS maybe configured to place data on one or more downstream channels orfrequencies to be received by devices, such as modems at the varioususer sites 102 (e.g., homes or office buildings), and to receiveupstream communications from those modems on one or more upstreamfrequencies. Because the network 100 provides services to user at theuser sites 102, the network 100 may also be referred to as a serviceprovider network. The network equipment site 103 may also include one ormore network interfaces 108, which can permit the network equipment site103 to communicate with various other external networks 109. Thesenetworks 109 may include, for example, the Internet, telephone networks,cellular telephone networks, a PON or other type of fiber opticnetworks, local wireless networks (e.g., WiMAX), satellite networks,managed services networks, and/or any other desired network. Thesenetworks 109 may also be communicatively coupled to, e.g., one or moreweb servers 119 that are responsible for hosting Internet or Intranetweb pages and/or one or more databases 120 (which may be implemented byweb servers 119 and/or separately from web servers 119). The networkinterface 108 may include the corresponding circuitry and/or devicesneeded to communicate on the network 109, and to other devices coupledto the networks 109 such as a cellular telephone network and itscorresponding cellular phones, such as cellular phone 116A and/or otheruser devices.

As noted above, the network equipment site 103 may include a variety ofservers 106-107 that may be configured to perform various functions. Forexample, the network equipment site 103 may include a content server106. The content server 106 may be one or more computing devices thatare configured to provide content to users in the homes. This contentmay be, for example, multimedia content such as video on demand movies,television programs, songs, text listings, etc. The content server 106may include software to validate user identities and entitlements,locate and retrieve requested content, encrypt the content, and initiatedelivery (e.g., streaming) of the content to the requesting user and/ordevice.

The network equipment site 103 may also include one or more applicationservers 107. An application server 107 may be a computing deviceconfigured to offer any desired service, and may run various languagesand operating systems (e.g., servlets and JSP pages running onTomcat/MySQL, OSX, BSD, Ubuntu, Redhat, HTML5, JavaScript, AJAX andCOMET). For example, an application server may be responsible forcollecting data such as television program listings information andgenerating a data download for electronic program guide listings.Another application server may be responsible for monitoring userviewing habits and collecting that information for use in selectingadvertisements. Another application server may be responsible forformatting and inserting advertisements in a video stream beingtransmitted to the homes 102. Yet another application server may beresponsible for inserting other information such as optically readablecodes (e.g., quick response codes, also known as QR codes) into a videostream.

An example home or other location 102 a may include a device 110, suchas a modem, which may include transmitters and receivers used tocommunicate on the links 101 and with the network equipment site 103.The device 110 may be, for example, a coaxial cable modem (where thelinks 101 are or otherwise include coaxial cable lines at the customerpremises), a fiber interface node (where the links 101 are or otherwiseinclude fiber optic lines at the customer premises), or any otherdesired modem device. The device 110 may be connected to, or be a partof, a gateway device 111 (gateway 111). The modem 110 and/or the gateway111, either alone or together, may be considered herein an example of aninterface 120 that may provide the user's devices with network access.The modem 110 and the gateway 111 may be physically separate entities orintegrated together as a single device, such as in a common housingand/or rack.

The interface 120 may be or otherwise include one or more devices suchas customer premises equipment (CPE) devices. For instance, theinterface 120 may be physically located in, or otherwise at, theresidence, office, or other building of the user served by the interface120. Any or all of local devices 112-117 may also be co-located with theinterface 120, such as in the same building or campus as the interface120.

The gateway 111 may be or otherwise include a computing device thatcommunicates with modem 110 to allow one or more other devices in thehome to communicate with the network equipment site 103 and otherdevices beyond the network equipment site. The gateway 111 may be orotherwise include, for example, a set-top box (STB), digital videorecorder (DVR), computer server, local-area network (LAN) router, or anyother desired computing device. The gateway 111 may include LANinterfaces to route and/or otherwise provide communication signalsto/from local devices in the location 102 a, such as one or moretelevisions 112, one or more DVRs or other types of content recorders113, one or more personal computers 114 and/or 115, one or more wirelessdevices 116B (wireless laptops and netbooks, cellular phones, mobiletelevisions, personal digital assistants (PDA), etc.), one or morevoice-over-IP (VoIP) phones 117, one or more gaming consoles 121, andany other desired devices. Examples of the LAN interfaces includeMultimedia Over Coax Alliance (MoCA) interfaces, Ethernet interfaces,universal serial bus (USB) interfaces, wireless interfaces (e.g., IEEE802.11), Bluetooth interfaces, and others. While many of the userdevices and/or content consumption devices are shown coupled to otherportions of the system via links 101 and interface 120, any of thesedevices may be coupled to other portions of the system in any mannerdesired. For example, the devices for a given user may not be situatedat a single location and may not be coupled to the network via the sameinterface. Moreover, any of these devices may be coupled to otherportions of the system 109 without necessarily requiring an interveninginterface device. As an example, cellular phone 116A is independentlycoupled to the network 109 without a separate interface device.

FIG. 2 illustrates an example of general hardware and/or softwareelements that can be used to partially or fully embody any of thevarious devices and functions discussed herein, such as any of thoseelements discussed herein with regard to FIG. 1. A computing device 200(also often referred to as a computer) may include one or moreprocessors 201, which may execute instructions of a computer program toperform any of the features described herein. The instructions may bestored in any type of tangible and/or non-transitory computer-readablemedium 202, such as a memory or hard drive, to configure the operationof the processor 201. For example, instructions may be stored in aread-only memory (ROM), a random access memory (RAM), a removable mediasuch as a Universal Serial Bus (USB) drive, compact disk (CD) or digitalversatile disk (DVD), a floppy disk drive, an attached (or internal)hard drive, and/or any other desired data storage medium. The computingdevice 200 may include or be coupled to one or more output devices, suchas a display device 205 (e.g., an external television, or a computermonitor), and may include one or more output device controllers, such asa video processor. The display device 205 may be physically separatefrom the computing device 200, or it may be integrated with theremainder of the computing device 200. There may also be one or moreuser input devices, such as a remote control, camera, keyboard, mouse,touch screen, microphone, etc. The computing device 200 may also includea communication interface 204, which may include one or more inputand/or output circuits (e.g., in the form of a network card) tocommunicate with an external device or network (e.g., network 109). Thecommunication interface 204 may be a wired interface, wirelessinterface, or a combination of the two. In some embodiments, such aswhere the computing device embodies the interface 120, the communicationinterface 204 may include modem 110 (e.g., a cable modem), and thenetwork may include, for example, the communication links 101 discussedabove, TS 104, the external network 109, an in-home network, aprovider's wireless, coaxial, fiber, or hybrid fiber/coaxialdistribution system (e.g., a DOCSIS or PON network), and/or any otherdesired network.

FIG. 3 is a plan view of an example remote control 300 that may be usedwith, e.g., a the interface 120 and/or a content consumption device(e.g., DVR 113, computer 114, or gateway 111). Remote control 300 may beimplemented as, for example, the above-mentioned remote control for usewith computing device 200. In this example, remote control 300 mayinclude a body (e.g., a housing) 301, on which one or more user inputand/or output elements are exposed to the user. In this example, suchelements may include one or more buttons, such as button 302. Inaddition, remote control 300 may include a wireless communicationelement 303 such as an infra-red and/or radio frequency (e.g.,BLUETOOTH) emitter for unidirectional or bidirectional wirelesscommunication with another device, such as gateway 111. Alternatively,remote control 300 may communicate with another device via a wiredconnection. Remote control 300 may also include a camera 304 forobtaining an optical image.

In some embodiments, remote control 300 may be a dedicated orspecialized remote control device. In other embodiments, remote control300 may be embodied as a portion of another device or as a function of adevice having larger functionality. For example, cellular phone 116B oranother mobile device may include, or otherwise be used as, remotecontrol 300. In any of these embodiments, remote control 300 may furtherbe implemented as a computing device such as computing device 200. Thus,in some embodiments, wireless communication element 303 may beimplemented as communication interface 204. Moreover, where remotecontrol 300 includes communication interface 204, remote control 300 maybe capable of communicating (in a wired and/or wireless manner) withother devices or networks, such as network 109.

As will be described further, a device under the control of a user, suchas remote control 300, cellular phone 116A, cellular phone 116B, orlaptop 115, may be used to obtain an image of an optically readablecode, and to take a particular action based on the obtained image. Anoptically readable code may be embodied as a printed pattern on asubstrate (such as paper, cardboard, wood, or plastic) or as a displayedpattern (such as on a display device) viewable by a camera and/or by ahuman eye, and may encode or otherwise contain information that may beinterpreted by a computer and/or by a human. Examples of an opticallyreadable code include, but are not limited to, a QR code, a bar code, adot array code, or a code using some other patterning of symbols.Moreover, the optically readable code may be formatted such that a humantypically may not be able to read the code. For instance, the codeand/or the parameters encoded by the optically-readable code may not beformatted in any human language (a non-human-language code), but ratherin a machine-readable language. Thus, for example, the parametersrepresented by an optically-readable code may not be represented asplain letters, numbers, and/or other characters in a human-language textformat.

Two example instances of QR codes are shown in FIG. 1: elements 150A and150B. In these examples, the QR codes 150A and 150B are two-dimensionalcodes using two colors (black and white). However, an optically readablecode such as a QR code may be a one-dimensional code, a two-dimensionalcode, or a three-dimensional code (e.g., a holographically printed ordisplayed code), and may encode information using two or more colors.Moreover, while a particular format of QR code is shown in FIG. 1, thereare several other conventionally-known QR code formats that use multiplecolors and/or other encoding patterns, and there will likely be new QRcode formats developed in the future. The present discussion is notlimited to any particular QR code format, or any particular format ofany other type of optically readable code. Thus, any references hereinto a specific format of optically readable code are merely by way ofexample.

As will be discussed below by way of example, an optically readable codemay be imaged by any device under the user's control having a camera,such as cellular phone 116A, cellular phone 116B, or laptop 115. Theimage may be interpreted by the device to obtain the information encodedby the optically readable code. Software applications for interpretingoptically readable codes such as QR codes are well known.

The information encoded by the optically readable code may represent,e.g., a universal resource indicator (URI) such as a universal resourcelocator (URL). The device may execute web browser software that iscapable of browsing to the URI indicated by the optically readable code.For example, the device may send a hypertext transfer protocol (HTTP)request over network 109 to a domain name server (DNS) that serves apacket-switched network such as the Internet. The DNS may then directthe device to an Internet Protocol (IP) address associated with the URI.The IP address may be the IP address of a server, such as web server119, that provides a desired web site.

The URI encoded by the optically readable code may further include oneor more parameters (e.g., passed parameters). As will be discussedbelow, the parameters may provide the basis for a query associated withthe web site. The query may be sent to a database, such as database 120,and the database may return results of the query back to the server. Thequery results may be used to customize the content provided to theuser's device by the website. As will be further described below by wayof example, the parameters may together represent a query of a databaseof content selections, such as audio and/or video content (e.g., filesand/or streams), television programs, movies, on-demand content, etc.Moreover, the results of the query, which may indicate a selectedcontent item, may be used to send a command to a media recording device(such as a DVR) to record the selected content. The term “content” asused herein may include, for instance, content that comprises audio,video, and/or other data such as closed captioning information and/orother metadata, and/or that includes three-dimensional video content.The term “video content” as used herein may include solely video(including two-dimensional and/or three-dimensional video content), andmay further include content that comprises video in addition to one ormore other types of content such as audio and/or the above-mentionedother data.

FIG. 4 is a flow chart of example steps that may be performed inaccordance with one or aspects as described herein. In this example, thesteps may be variously performed by a user device having a camera (e.g.,cellular phones 116A or 116B, or remote control 300), one or moreservers (e.g., web server 119), and/or a content consumption device(e.g., display device 205, DVR 113, computer 114, or gateway 111). Atstep 401, the user device may be used to obtain an image of an opticallyreadable code with the camera of the user device. The optically readablecode may be encountered by the user on any media in any environment, athome or outside the home. For example, the optically readable code maybe printed on a substrate such as on a conventional highway billboard,on a poster, in a magazine, in a newspaper, or in a book, or displayedsuch as on a website, a video billboard, or on another type ofelectronic advertisement display.

The optically readable code may encode information related to theenvironment (e.g., substrate) on and/or in which the optically-readablecode is presented. For example, a printed advertisement for a particulartelevision series may include an optically readable code that encodes aURI containing parameters sufficient to define a query, such that thequery would result in one or more episodes of the television series (orthe entire series) being the selected content. Thus, in this example,the user device may obtain an image of the optically readable code, andin response the user device's web browser may be automatically directedto a query result of a web site, where the query result has selected theone or more episodes of the television series. The user's contentconsumption device (e.g., a smart phone, audio system, DVR, set top box,display device, or computer) may then be commanded to record, tune to,display or otherwise present (e.g., via audio speakers), obtain, and/orotherwise process the selected one or more items (e.g., items of videocontent). This may all occur even though the user may be physicallyremote from the content consumption device.

As an example, suppose the user is walking and sees a billboardadvertisement for the television series, “30 Rock” that includes anoptically-readable code. The user may pull out the user's mobile device(e.g., smart phone) and take a picture of the optically-readable codeusing a software application for reading optically-readable codes, suchas a QR code reader application. The optically-readable code may includethe parameters representing values of characteristics, where if a queryincluded the values, the query would be sufficient to return an item ofcontent (in this case, the series “30 Rock” or an episode thereof) as aresult of the query. For instance, the characteristics may include thetitle of the series (“30 Rock”) or of an episode of the series, thestart time of the series, the recording time, the channel on which theseries will be presented, the day and/or date of the series, thefrequency of presentation of the series, etc.

Thus, returning to FIG. 4, at step 402 the user device (e.g., theoptically-readable code reader application) may interpret the image ofthe optically readable code as discussed above to extract the encodedURI and/or the included parameters. The parameters may be appended tothe path of the URI, such as in the form of a query string in accordancewith the syntax set forth in RFC 3986. For example, the opticallyreadable code may represent the following URI with parameters:

-   -   https://secure.api.company.com/widgets/stage/dvr/search/Fseries/program?search        Value=D7705238&searchLimitDays=7&maxResults=25&api_key=synddemo

Thus, the URI in this example may include a name of a web server(“secure.api.company.com”), a path in the server(“/widgets/stage/dvr/search/Fseries/program”), and various parametersalong with the values of those parameters beginning after the “T”character. In the above example, the parameters may indicate that thevalue of the searchValue parameter is D7705238, the value of thesearchLimitDays parameter is 7, the value of the maxResults parameter is25, and the value of the api_key parameter is synddemo. In more generalterms, the parameters may take the form of, e.g.,parameter1=value1&parameter2=value2&parameter3=value3, etc. This is butone example of how parameters may be included in a URI. Another examplemay be to use standard percent-encoding of reserved characters in thequery string rather than directly using reserved characters such as “?”,“/”, and “=”.

Next, the URI may be browsed-to by the web browser of the user device.This may involve a DNS lookup, and once the URI is resolved by the DNS,in step 403 a message (such as an HTTP message) may be directed by theuser device over a network such as the Internet to the appropriateserver (e.g., web server 119) associated with the resolved URI. Themessage may include the URI and/or the parameters.

Examples of parameters that may be passed to the server (and utilized ina query) may include the title of a desired item of content, a key word,a content type (e.g., television program, series, movie, on-demandcontent), a length or range of lengths, a start time or range of starttimes (which may include date, day, week, month year, and/or time ofday), a frequency of showings or set of frequencies of showings (e.g.,weekly, monthly), a rating or set of ratings (e.g., G rated, PG-13rated), a channel or set of channels, a content provider or set ofcontent providers (e.g., NBC, CBS, HBO), a search time range, and amaximum number of results. These are merely examples; other types ofparameters may additionally or alternatively be passed and utilized in aquery.

At step 404, the server to which the message was directed may receivethe message and cause a query of a database (such as database 120),using the parameters, to be performed. The parameters may be combined asappropriate, such as by Boolean ANDing each parameter value definitiontogether. For instance, if the URI in the message is as shown in theexample above, the query may define the values of the parameters asfollows: (searchValue=D7705238 AND searchLimitDays=7 AND maxResults=25AND api_key=synddemo).

The results of the query may be returned to the server, and the servermay present (at step 405) a user interface referred to herein as aprogramming control page (such as a web page) to the user device. Anexample of such a programming control page is shown in FIG. 5. Theprogramming control page may be presented by the server as, e.g., anHTML page, and may present results of the query performed at step 404.In the present example, the programming control page may show that thequery returned the result of a TV Series entitled, “NCIS,” along withthe showing frequency, time, length, channel, and content provider (inthis example, Tuesdays, starting at 8 pm, length one hour, channel 29,CBS). The programming control page may also show a recommended recordingcommand—in this case, record the series. Upon logging in to the user'saccount with a user ID and password (to prevent unauthorized access tothe user's content consumption device), the user may select the Recordbutton if the user would like to cause the current recording command(record series) to be performed for the indicated television series. Therecording command may also include other default settings, such as thatthe recording start time will be at the time that the indicated contentbegins and will last for the indicated content length. If the userwishes to change any of these settings, the user may select the ChangeRecord Settings button to do so. The user may also select a particularcontent consumption device is there are multiple such devices associatedwith the user's account.

Thus, at step 406, the user may interact with the programming controlpage by modifying settings and/or selecting a command such as Record.Responsive to the user selecting the Record button of the programmingcontrol page, at step 407 the server may detect this and cause a commandto be sent to the content consumption device associated with the user'saccount. The command may be sent over a network such as network 109. Inthe above example, the command may include a record command includingthe details of the recording to be made (e.g., an indication of whichcontent is to be recorded, the time that the recording should begin, thelength of the recording, the channel, etc.). In further embodiments, theuser may select that the command be a “tune to” command rather than arecord command, such that the content consumption device tunes to theselected content at the appropriate time without recording the content.

At step 408, the content consumption device may receive the command andset up a scheduled future recording of the indicated content (or ascheduled future tuning to the indicated content). At step 409, thecontent consumption device may send a confirmation message back to theserver that the command has been successfully received and interpreted,and/or that the recording or tuning has been scheduled. At step 410, theserver may receive the confirmation message from the content consumptiondevice, and in response may provide, at step 411, an indication (such asvia the programming control page) to the user device of theconfirmation.

In various examples discussed above, the URI as well as the parameterspassed therein may be encoded in an optically readable code such as a QRcode. While the optically-readable code may be printed on a physicalsubstrate such as a billboard or magazine, the optically-readable codemay alternatively be presented on a display device such as a televisionor a computer display. For example, a QR code or other opticallyreadable code may be caused to be displayed by the content consumptiondevice (e.g., DVR 113, television 112, gateway 111, or computer 114).Moreover, the content consumption device may be configured to display anoptically readable code responsive to a user input indicating a desireto view the optically readable code, and to otherwise not display theoptically readable code. This may be useful where, for instance, theoptically readable code that is to be displayed depends upon the contentcurrently being rendered/displayed or otherwise presented by the contentconsumption device. For example, referring to FIG. 6, an item of contentmay be divided into a plurality of portions, each portion beingassociated with one or more optically-readable codes. In this example, afirst portion (Video Segment A) is associated with an optically readablecode (designated in the figure as optically-readable code 1), a secondportion (Video Segment B) is associated with a different opticallyreadable code (designated in the figure as optically-readable code 2),and a third portion (Video Segment C) is associated with still otheroptically readable codes (designated in the figure as optically-readablecodes 3 and 4).

Such on-demand and/or context-sensitive optically-readable codes mayprovide a useful service to the user in a variety of ways. For example,where the content includes advertisements, there may be a different oneor more optically readable codes associated with each of theadvertisements. A user request for the context-sensitiveoptically-readable code may result in one or more optically-readablecodes relevant to the advertisement currently being presented to theuser. Once the optically-readable code is displayed, the user may use auser device, such as cellular phone 11B, by pointing the camera of theuser device toward the display device and obtain an image of theoptically-readable code. In response, the user device may browse to theweb page indicated by the optically-readable code to obtain informationabout the advertised product or service.

As another example, the content may involve a contest or otheruser-interactive feature. For instance, the content may be video contentof a dance competition amongst three contestants, where the viewers ofthe content are allowed to vote for the winner. In this case, a userrequest may result in an on-demand display of a separateoptically-readable code representing information about and/or a vote forthe respective contestant. Obtaining the image of the desired one of thedisplayed optically-readable codes by the user device may result in theuser device browsing to an appropriate web page indicated by theoptically-readable code. This may provide the user with additionalinformation about the contestant and/or allow the user to register avote for the competitor.

As yet another example, a sports game (e.g., baseball or basketball) maybe the content being presented (e.g., the video content beingdisplayed). When optically-readable codes are summoned by the user, thecodes may represent web pages containing information about the players.The particular codes displayed may depend upon which of the players arecurrently playing, which is/are currently in possession of the ball,which is/are currently being discussed by the sports commentator, etc.,at the time that the user request is made. In some cases, especiallywhere the content is live content rather than pre-recorded content, theoptically-readable codes may not be predetermined until immediatelyprior to the viewing of the optically-readable codes by the user. Insuch a case, the optically-readable codes may be determined inreal-time, such as by a human operator.

As still another example, the context-sensitive displayedoptically-readable code may represent a database query designed toreturn another item of content for recording, such as describedpreviously in connection with the example of FIG. 4.

Decisions as to which optically-readable codes are associated with whichcontent portions may be made manually, by a human, and/or automaticallyby a computer. In the latter case, the computer may be configured torecognize optical and/or audio features in the content in order todetermine how the content should be divided into portions and/or toautomatically assign optically-readable codes to the various portions.

Thus, in general, the network server and/or the content consumptiondevice may be configured to provide on-demand context-based opticallyreadable codes, where the optically readable code depends upon whichcontent, or portion thereof, is currently being presented to the user ofthe content consumption device. FIG. 7 is a flowchart of an example setof steps that may be performed by such a network server and/or contentconsumption device that provides on-demand and/or contextually-generatedoptically readable codes. At step 701, the content consumption devicemay be currently presenting (e.g., displaying), or causing to bepresented, content to the user. The content may already be stored, forexample, locally by the content consumption device (e.g., in the case ofthe content consumption device being a DVR). Alternatively, the contentmay be actively streaming from the service provider (e.g., along line101) to the content consumption device while the content is beingconsumed by the user. In the latter case, at least some of the contentmay further be locally buffered and/or recorded by the contentconsumption device while the content is being presented to the user. Ineither case, at step 702, while the content is being presented to theuser, the server and/or content consumption device may determine that alocal user input has been received. For example, the user might pressbutton 302 of remote 300 (where remote 300 is in communication with orpart of the content consumption device).

In response to detecting the user input, at step 703, the server and/orcontent consumption device may determine which optically readable codeis to be displayed based on the status of the content consumptiondevice. For instance, the status of the content consumption device mayinclude which content, and/or which portion thereof, is currently beingpresented to the user. As will be discussed below with regard to FIGS.12 and 14, the status may additionally or alternatively include anidentity of the content consumption device and/or an operating status ofthe content consumption device, such as an error condition experiencedor otherwise detected by the content consumption device.

To determine which contextual optically readable code(s) to display ondemand, the content consumption device may utilize locally-storedinformation and/or information requested from the service providernetwork. For example, the content consumption device may receive datafrom the service provider network representing data (e.g., a table)associating timestamps or timestamp ranges (or other content portions)of the video being displayed with optically readable codes. In such acase, each optically readable code may have a unique identifier, and sothe table for the content being consumed (and/or for other content) mayassociate time stamps or timestamp ranges with the identifiers. Theremay be a table for each item of content. If the content includestimestamp data, then the content consumption device may use the table todetermine the optically readable code to be displayed based on thetimestamp of the portion of the content being presented to the user atthe time that the user input is received. The optically readable codemay contain information relevant to a particular portion of and/orlocation within the content. The content consumption device may thenretrieve the determined optically readable code(s) from local storage orby sending a request to the service provider network (where the requestis directed to, e.g., the content server 106 or the application server107) indicating the determined optically readable code identifier(s) andreceiving the appropriate optically readable code(s) in return (e.g.,from the content server 106 or the application server 107).

Alternatively, where the content consumption device does not have localaccess to such a table or other associating data, the contentconsumption device may send a request (where the request is directed to,e.g., the content server 106 or the application server 107) indicatingthe time of the user input and/or the currently presented content to theservice provider network. In return, the service provider network mayprovide the optically readable code(s) associated with the indicatedtime and/or content. Or, where the request simply indicates theexistence of the user input (and/or and identification of the contentbeing presented), the service provide network may determine the time therequest is received and return the associated optically readable code(s)to the content consumption device.

In still further embodiments, the optically readable codes may beincluded in the data stream of the content itself, or in another datachannel received simultaneously with the content. For example, as newoptically-readable codes become relevant over the different portions ofthe content being presented (e.g., displayed), those optically-readablecodes (and/or identifiers of those optically-readable codes) may beembedded in the content data and/or in associated parallel real-timedata. In these cases, to determine the appropriate optically-readablecode(s), the content consumption device may read the currentoptically-readable code (and/or the identifier thereof) directly fromthe content data and/or from the parallel real-time data channel.

Thus, depending upon the particular embodiment, at step 704, the contentconsumption device may obtain the determined optically readable code(s)from local storage or from the service provider via the service providernetwork.

Regardless of how the optically readable code(s) is/are obtained, atstep 705, the content consumption device may display (or cause to bedisplayed) the context-sensitive optically readable code to the user.The optically readable code may be displayed simultaneously with thecontent, such as in an overlay configuration or in a side-by-sideconfiguration where the content includes video content. Alternatively,the optically readable code may be displayed instead of the videocontent, where the video content may continue or be automaticallypaused. The optically readable code may continue to be displayed until,for example, the optically readable code has been displayed for apredetermined period of time (e.g., until a timeout has occurred), orresponsive to the user providing an appropriate user input indicatingthat the optically readable code should no longer be displayed, orresponsive to the user selecting a different item of content to bepresented.

FIG. 8 shows an example of how an on-demand (e.g., requested) and/orcontext-sensitive (e.g., time dependent/sensitive) optically readablecode may be displayed. In this example, the content consumption deviceor the display device presents video content 801, when the user input isreceived by the content consumption device. The content consumptiondevice may, in response, determine the contextually appropriateoptically readable code, and display it such as in an overlay manner. Anexample of this is shown in which optically readable code 802 isdisplayed as an overlay over the video content 801. As previouslydiscussed, there are other possible ways to display the opticallyreadable code 802, such as in a side-by-side format with the videocontent 801, and/or to temporarily remove the display of the videocontent 801 while the optically-readable code 802 is being displayed.

FIG. 9 shows another example of how multiple on-demand (e.g., requested)and/or context-sensitive optically readable codes may be simultaneouslydisplayed. In this example, the content consumption device is againcausing the display device to display the video content 801, when theuser input is received by the content consumption device. The contentconsumption device may, in response, determine the contextuallyappropriate optically readable codes, and display these codes such as inan overlay manner. An example of this is shown in which opticallyreadable codes 901 and 902 are displayed as an overlay over the videocontent 801. Again, this is merely an example, and the codes 901 and 902may be displayed in a variety of other ways. Also in this example, itcan be seen that a text label is displayed adjacent to eachoptically-readable code 901, 902, to indicate what eachoptically-readable code represents. In this case, the labels indicatethat the two optically-readable codes 901, 902 represent a different oneof two contestants (where, e.g., the video content 801 is a competitionbetween Contestant A and Contestant B). The labels may additionally oralternatively include other information, such as graphical and/oranimated information.

FIG. 10 is another example screen shot of information that may bedisplayed by the content consumption device in conjunction with anoptically-readable code. In this example, a schedule 1001 of contentitems is displayed. Such a schedule is sometimes referred to as aprogram guide. Typically, the user can interact with a program guidesuch as this by selecting an item of content and requesting that theitem be recorded or presented (e.g., displayed), or to obtain furtherinformation about the selected item. In the present example, twelveitems of content (Item 1 through Item 12) are shown, and Item 4 ispresently selected. An optically-readable code 1002 may further bedisplayed that corresponds to the selected item, and may be formatted inany of the manners discussed herein. For example, the optically-readablecode 1002 may represent a URI including parameters that in turnrepresent parameters in a database query. Moreover, theoptically-readable code 1002 may be displayed automatically uponselection of an item of content, or it may be displayed on-demand onlyresponsive to a specific user input requesting that theoptically-readable code 1002 be displayed. The latter may be desirablewhere it is not efficient to always set aside screen real estate for theoptically-readable code 1002, especially where some users may not oftenutilize such a code.

In any of the above-described example embodiments, an advertiser orother entity may desire to create the optically-readable code so that itis sufficient to initiate the appropriate database query. This may bedone in a number of ways, including on a trial-and-error basis. FIG. 11shows example steps that may be performed by an advertiser or otherentity to determine and create an optically-readable code. Some or allof the steps of FIG. 11 may be performed manually, by a human, and/or bya computer executing software.

At step 1101, the entity may determine one or more characteristics ofthe desired item(s) of content. For example, the entity may desire thatthe optically-readable code include a query leading to a result thatincludes a particular television series. The characteristics may includeone or more of, for instance, the title of a desired item of content, akey word, a content type (e.g., television program, series, movie,on-demand content), a length or range of lengths, a start time or rangeof start times (which may include date, day, week, month year, and/ortime of day), a frequency of showings or set of frequencies of showings(e.g., weekly, monthly), a rating or set of ratings (e.g., G rated,PG-13 rated), a channel or set of channels, a content provider or set ofcontent providers (e.g., NBC, CBS, HBO), a search time range, and amaximum number of results. These are merely examples; othercharacteristics of the desired item(s) of content may additionally oralternatively be used to determine the query.

Next, at step 1102, the entity may perform a query of theabove-described database by, e.g., generating a URI including parametersrepresenting parameters of the query, and sending a message containingthe URI to the web server 119 via a network. The web server 119 mayreturn results of the query back to the entity, and at step 1103, theentity may review the results.

If it is determined at step 1104 that the results are as expected (e.g.,the results identify the desired item(s) of content), then the query maybe considered to return the correct results, and so the process may moveto step 1106. At step 1106, the entity may create an optically-readablecode that encodes the previously-determined URI including theparameters. The optically-readable code may be stored as data on acomputer-readable medium and/or visibly printed onto a physicalsubstrate such as a billboard, magazine, newspaper, or book (e.g., usingink, toner, or another substance). Additionally or alternatively, datarepresenting the optically-readable code may be sent to a display deviceso that the optically-readable code may be displayed (such as in step705 of FIG. 7).

If it is determined at step 1104 that the results are not as expected,then the query may be modified to further narrow or broaden the query,or to change the query in other ways. For instance, it may be realizedthat too many search results are provided, and that one or moreadditional query parameters should be added. The process may then moveback to step 1102 in order to execute the new query and to subsequentlyanalyze the results thereof in step 1103.

As discussed previously, the interface 120 or content consumption devicemay be controlled by a remote control device, such as remote control300. In some situations, it may be desirable to pair a particular remotecontrol device with a particular network access device (e.g., interface120) and/or a particular content consumption device, so that the remotecontrol device is authorized to control that device. Pairing in generalof a device with its remote control is known, and may be done, forinstance, by having a user enter a secret authorization code into theremote control, where the authorization code is provided by the deviceto be controlled. However, this type of device pairing is not alwaysuser-friendly, can be inconvenient, and is error-prone due to the humaninput that is normally required. Another way to pair devices isproposed, where one of the devices is able to cause information to bedisplayed (such as on a television or other display device) and theother of the devices is able to view the displayed information (such asvia a camera). For instance, the device to be controlled (e.g., acontent consumption device) may display an optically readable coderepresenting specific information, and the remote control device mayread the optically readable code and use the specific information topair the remote control device with the device to be controlled. Anexample of such a process is described with respect to the flow chart ofFIG. 12.

In the example of FIG. 12, a user device such as remote control 300 orcellular phone 116B may be paired with a content consumption device orone or more other devices as follows. At step 1201, the user device maysend a request to the content consumption device for a device statuscode. This may be instigated by, for instance, the user commanding theuser device to send such a request. In response, the process moves tostep 1202. Alternatively, the content consumption device may performstep 1202 without waiting for a request from the user device. Forinstance, the user may command the content consumption device to beginperforming step 1202, such as by selecting a pairing function on thecontent consumption device.

At step 1202, the content consumption device may determine a status ofitself, and determine status information from the status. The statusinformation may include, for example, an identifier of the contentconsumption device. The identifier may be, for instance, a networkaddress such as an IP address, MAC address, and/or serial number. Thestatus information may further include a power status of the contentconsumption device, such as whether the content consumption device iscurrently in an “on” or “standby” state. The status information mayfurther include which one or more channels, frequencies, programs,content, and/or streams that the content consumption device is currentlydisplaying or otherwise presenting, tuned to, recording, or otherwisereceiving. The status information may further include a password orother secret key that is not normally publicly shared and that isuniquely associated with the content consumption device and/or with aparticular user of the content consumption device. The statusinformation may include only one or another subset of these items ofinformation, and/or it may include completely different information.Whatever the status information is for a particular embodiment, thestatus information may be displayed in a format that is understandableby the user device. For example, the status information may be encodedinto an optically-readable code, which may then be displayed (step 1203)on a display device, such as television 112, a computer monitor, or anyother display device.

An example of an optically readable code that may be generated at step1203 is shown in FIG. 13. The example optically-readable code of FIG. 13may represent the following status information:

-   -   MAC Address: AE68FF    -   Status: On    -   Frequency: 192 MHz    -   Video PID: 198    -   Audio PID: 17    -   Transport Stream ID: 1234

At step 1204 of FIG. 12, the user device may read the displayedoptically readable code, such as by using a camera of the user device.At step 1205, the user device may decode the optically readable code toobtain the status information, and configure itself in a manner based onsome or all of the status information. Configuring may involve, forinstance, storing some or all of the status information in memory,and/or executing instructions causing the user device to utilize some orall of the status information when interacting with the server such asin step 1205. The user device may now have sufficient information to bepaired with the content consumption device. In other words, the userdevice may have sufficient information to be able to successfullycontrol one or more functions of the content consumption device thatwould otherwise not be controllable without that information. Forinstance, the content consumption device (or any intermediate devicesuch as a server) may ignore certain commands from the user deviceunless the user device is authorized, such as by including with thosecommands an indication of the identifier (e.g., MAC address) of thecontent consumption device, or unless the command includes the key.

The user device may now be authorized to command the content consumptiondevice via the network. To do so, at step 1206, the user device mayinteract with the server, such as by sending a message to the serverrequesting that the content consumption device perform some function,such as changing the channel, recording a show, turning on, turning off,pausing, playing, fast forwarding, rewinding, displaying a list ofrecorded content, displaying an electronic program guide, etc. Themessage may include the above-mentioned indication indicating that theuser device is authorized to control the content consumption device.Additionally or alternatively, the user device may directly control thecontent consumption device.

In response to the message from the user device, at step 1206, theserver may generate and send an appropriate command to the contentconsumption device, based on the message received from the user device.At step 1208, the content consumption device may act on the command(e.g., by performing the requested function).

As previously discussed, the content consumption device may generate anddisplay an optically readable code indicating a status of the contentconsumption device. The status may include, for example, an errorcondition experienced by and/or otherwise detected by the contentconsumption device. In such a case, the content consumption device maybe configured to generate and display an optically readable codeindicating the particular error condition, such as by an error code orother identifier of a particular error condition. Error conditions thatmay trigger display of an associated optically readable code may beindicative of problems experienced by the content consumption device,such but not limited to, loss of network connectivity (upstream and/ordownstream), poor quality signal, failed hardware (e.g., a failed harddrive) of the content consumption device, failed functionality of thecontent consumption device, overheating, incorrect connectivity to otherdevices, failed response from other connected devices, outdated firmwareand/or software, low battery state, loss of external power, and thelike. The error condition may additionally or alternatively beindicative of a problem experienced by the user of the contentconsumption device, even though the device may be operating and/orconnected as designed, such as but not limited to, inappropriate userinput such as incorrect password entry, improper menu selection, and thelike.

The displayed optically readable code may be read such as in the mannerspreviously described (e.g., using a user device such as a cell phone orother device having a camera). The user device may then interact with aserver or other device by providing the server with an indication of theerror condition represented by the optically readable code. In turn, theserver may communicate helpful information to the user about the errorcondition, and/or the server may send a command to the contentconsumption device, in an effort to correct the error condition and/orto obtain further information about the error condition.

FIG. 14 is a flow chart of illustrative steps that may be performed toaccomplish one or more of the above-described features. At step 1401, acomponent in the network, such as the content consumption device, maydetect the occurrence of an error condition (such as one of the errorconditions listed above, or any other error condition). At step 1402,responsive to detecting the error condition, the network component(e.g., the content consumption device) may generate and display anoptically readable code to the user, where the optically readable codeis formatted so as to encode or otherwise represent an indication ofwhich error condition has occurred and/or other information related tothe error. Or, in the case of another network component, the networkcomponent may transmit the optically readable code to the contentconsumption device for display to the user. For example, where eacherror condition has a predetermined identifier (e.g., error code), theoptically readable code may represent at least the predeterminedidentifier for that error condition. The optically readable code mayfurther represent a website address. For example, the optically readablemay represent information such as:https://secure.api.company.com/errors/searchValue=12345. In this case,the optically readable code may represent a particular website and path,and a particular error condition having a predetermined error code of12345. Rather than displaying the optically readable code responsive todetecting the error condition, the content consumption device maydisplay the optically readable code in response to an external request,such as in response to user input and/or in response to a request from anetwork or externally-connected device.

At step 1403, the user device may be utilized to read (e.g., take apicture of) the displayed optically readable code. At step 1404, theuser device may decode the optically readable code to obtain informationencoded therein. Where the information represents a website or portionthereof, the user device may use a web browser of the user device tobrowse to the indicated website location. Alternatively, the user devicemay communicate with a server without the use of a web browser, bysending the server or another network component the error coderepresented by the optically readable code (e.g., to be interpreted bythe server or another network component).

Thus, at step 1405, the server (e.g., a computing device such as the webserver 119, application server 107, and/or another server), may receivethe error code and may determine how to proceed based on the error code.For example, the server may determine, based on the error code, thatinstructions or other information may be provided to the user device fordisplay by the user device (step 1407), such as via the web browser or aspecialized software application of the user device. The information mayinclude, for example, step-by-step instructions as to how to correct theerror condition (e.g., by providing certain input to the contentconsumption device, or by rebooting the content consumption device, orby asking the user to provide further information about thecircumstances of the error condition), and/or the information mayinclude helpful information such as a description of the meaning of theerror condition and what may be causing the error condition. Asappropriate, the user may provide one or more commands (step 1408) tothe content consumption device, such as in the form of direct userinput, upon the advice of the information provided by the server. Theuser may also perform subsequent interactions with the user device (step1410). In addition or alternatively, the server may send one or morecommands directly to the content consumption device (e.g., via links101) in an effort to correct the content consumption device and/orobtain further information about the error condition (e.g., by pingingthe content consumption device, sending a firmware update, or causingthe content consumption device to reboot). The content consumptiondevice may further provide feedback to the server as to the success orfailure, or other status, of the attempts to correct the errorcondition.

At step 1406, the content consumption device may act upon the one ormore commands provided by the server and/or the user. This may involve,for example, downloading a firmware update, or rebooting, or changing aninternal setting. This may further involve the content consumptiondevice providing feedback to the user as to the success or failure, orother status, of the attempts to correct the error condition, such as bydisplaying the feedback. At step 1409, the user may follow up withfurther interaction with the content consumption device, as appropriate.

Other variations on using an optically readable code are possible. Forexample, a user may use an optically readable code to access content ona content consumption device that is not necessarily associated with theuser and not necessarily accessible without a subscription,registration, or other service agreement. For instance, the user mayhave a subscription account with a content provider to be able toconsume content at the user's home device, mobile device, and/or otherdevice registered to the user. However, if the user is traveling orotherwise does not have access to the user's home device, the user couldconsume the content on an alternate content consumption device such asanother television, computer, mobile device, gaming device, tablet, etc.that may not be registered to the user with the content provider. Theuser may do so by, for example, invoking an optically readable code toappear on the other content consumption device, and using the user'sregistered mobile device to read the optically readable code. Thecontent provider may be able to partially or fully authenticate the userbased on a confirmation that the user's registered mobile devicesuccessfully read the optically readable code. This may imply that theuser actually has access to both the user's registered mobile device andthe alternate content consumption device, providing a level of trustthat the user is, in fact, who he or she says that the user is. Theability to access restricted content on a content consumption device notnormally associated with the user may be useful where, for instance, theuser is visiting the house of a friend or relative, or where the user isstaying in a hotel. In the first case, the alternate content consumptiondevice may be, e.g., a device owned or otherwise controlled by thefriend or relative. In the second case, the alternate contentconsumption device may be, e.g., a device owned or otherwise controlledby the hotel.

For example, say that a user is on a trip and is staying in a hotel. Thehotel may provide a content consumption device (e.g., anInternet-enabled television or computer) in each hotel room. In thisexample, the hotel-provided content consumption device would be thealternate content consumption device. For purposes of this example, itwill be assumed that the hotel-provided content consumption device is aninteractive Internet-enabled television set. The user may access theservice provider's server (e.g., browse to a web site) using the hotel'stelevision set to login to the user's account and cause an appropriateoptically-readable code to be presented on the hotel's television set.The user may then use the user's cell phone, tablet computer, or othermobile device known to the service provider and having a camera to takean image of the displayed optically-readable code. The user's mobiledevice may then use the information from the imaged optically-readablecode to authenticate the hotel's television set for the current viewingsession. By doing so, the service provider will be assured that anauthorized user is actually in the vicinity of the hotel's televisionset, and the service provider may then provide requested content to thehotel's television set that might otherwise be restricted from beingviewed without an agreement (e.g., subscription) between the user andthe service provider.

An example of how this process may work is described with reference toFIG. 15. At step 1501, the user may use the alternate contentconsumption device to request an optically readable code. This mayinvolve, for instance, the user logging in to a web site controlled orotherwise associated with the content provider and requesting anoptically readable code and/or to consume content on the alternatecontent consumption device. The web site may be hosted by, for examplethe web server 119 or the application server 107). For example, the usermay enter a user ID and/or a password to identify the user and/or theuser's account. At step 1502, a server of the content provider (e.g.,the server 119 or 107) may authenticate the user based on the log-inprocess and generate an optically readable code. At step 1503, theserver may cause the optically readable code to be displayed by thealternate content consumption device, such as via the displayed web pageof the web site and/or an information display screen. The opticallyreadable code may be generated in any of a number of ways, such asrandomly or selected from a predetermined set of optically readablecodes. For example, the optically readable code may identify apredetermined web site address (which may or may not be the same for allof the optically readable codes) and may further include one or moreparameters and/or a secret (such as a PIN or or one-time password). Theparameters and/or the secret may be randomly selected or selected from apredetermined set of parameters. Additionally or alternatively, theparameters and/or the secret may be at least partially based oninformation about the user and/or the user's account, such as the user'sname and/or account number, and/or based at least partially on thenetwork address of the alternate content consumption device (as may bedetermined at step 1504, especially if step 1504 is performed prior toor simultaneously with step 1502 and/or step 1503).

At step 1504, the server may also determine a network location of thealternate content consumption device, such as the IP address and/or MACaddress of the alternate content consumption device and/or of a localnetwork that includes the alternate content consumption device. Step1504 may be performed in a different sequence relative to the othersteps, such as prior to and/or simultaneously with step 1502 and/or step1503, or after or simultaneously with step 1507.

At step 1505, the user device (such as the cellular phone 116A or thecellular phone 116B) may be used to read and decode the displayedoptically readable code, such as by using a camera of the user device.At step 1506, the user device may transmit data representing the decodedinformation to the server or otherwise utilize the data to access theserver or a different server. For instance, where the decodedinformation represents a web site hosted by the server (or a differentserver) and/or supplemental information such as parameters, the userdevice may use a web browser or other software application to access theindicated web site and pass any such parameters to the server hostingthe web site. The decoded data may include, for instance, an indicationof the identity of the mobile device, an identity of the user, andidentity of the user's account with the content provider, and/or asecret as discussed previously.

At step 1507, the server (e.g., a computing device in a network) mayauthenticate the information provided by the user device and/or mayauthenticate the user device itself. This authorization may include, forexample, determining whether the data sent by the user device at step1506 is related to (e.g., the same as or otherwise based on) the datarepresented by the optically readable code. As an example, theoptically-readable code may include data representing theabove-mentioned secret. Thus, if the data sent by the user device atstep 1506 includes the secret, then this may result in successfulauthentication at step 1507. If authentication is successful, then theserver may assume that the user of the registered user device is locatedproximate to the alternate content consumption device. If so, then atstep 1508 the server may perform further processing to allow selectedcontent to be sent to (e.g., streamed to) and displayed or otherwisepresented by the alternate content consumption device. The content maybe selected, e.g., by the user via the alternate content consumptiondevice and/or via the user device. Moreover, such content may beviewable or otherwise consumable using the alternate content consumptiondevice until the user disables the alternate content consumption device,logs out of the web site, and/or after a predetermined window of time.For instance, the authorization to present content by the alternatecontent consumption device may be limited to a certain type of contentand/or a certain time period, such as twelve hours, or twenty-fourhours, after which time the alternate content consumption device may nolonger present restricted content without being successfullyre-authorized.

While embodiments of the present invention have been illustrated anddescribed, it is not intended that these embodiments illustrate anddescribe all possible forms of the present invention. Rather, the wordsused in the specification are words of description rather thanlimitation, and it is understood that various changes may be madewithout departing from the spirit and scope of the present disclosure.
